To all whom it may concern.-

Be it known that we, STEPHEN D LAYMAN and HANS (J. HANSEN, both citizens of the United States, and residing atBoston, in the county of Suffolk and State of Massachusetts, havejointly invented certain new and useful Improvements in Pin-Hole-Perforating Machines; and we do hereby declare that the same are fully described in the following specification, and illustrated in the accompanying drawings.

This invention relates to improvements in pinhole-perforating machines, forthe purpose of perforating sheets of paper, bristol-board, paper-board, and similar articles in one or more rows, parallel or crossing each other, according to the use for which the perforated article is intended.

The invention is carried out as follows, referenoe being had to the accompanying drawings, where Figure 1 represents a plan view, and Fig. 2 represents a side elevation, of the improved machine. Fig. 3 represents an enlarged crosssection on the line A B, shown in Fig. 1, and Fig. 4 represents an enlarged vertical section on the line C D, also shown in Fig. 1. Fig. 5 represents a modification of the machine asadapted for perforating the paper, &c., simultaneously with two or more parallelrows of holes. 7 i

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

or represents the table-top or work-supporting plate of the machine, preferably provided with a base frame or support, a, on its under side, that may be secured in a suitable manner to a bench or table, as may be found most convenient. To the tabletop a or its base a is cast in one piece or secured in a suitable manner the goose-neck I), having front and rear bearings, Hand 1), for the shaft 0, as shown in Figs. 1, 2, 3, and 4. To the rear end of shaft 0 is secured the fast pulley d, by means of which and a belt carried from a rotary pulley a rotary motion is imparted to said shaft 0. d is a loose pulley on shaft 0, as usual.

In front of bearing 1) is secured to shaft 0 the punch-wheel E, having its outer cylindrical portion made in theform of an annular rim, 6, between which and the annular projection e is made an annular groove, 6', as shown in Figs. 3 and 4. The rim eis provided with a number of radial perforations, in

which are inserted the punches e 0 that project a little outside of the outer periphery of punch-wheel E, as shown in Figs. 3 and 4, and have their inner ends resting against the annular projection or shoulder e, as shown in said figures. After the punches c e have been inserted through the perforations in rim '6 they are secured 1n place by means of a solder or alloy or molten metal, 6, run into the groove 6, as shown in Figs. 3 and 4. By having the punch-wheel E arranged upon shaft 0 outside of the bearing 12 papers of any width can be fed to the perforating device with greater freedom, as compared with machines in which such punch-wheel is located between two bearings. 7

Below the rotary punch-wheel E is located the die-wheel F, which latter is secured to the shaftf, as shown in Figs. 3 and 4. f is an annular rim at the periphery of the die-wheel F, which rim is provided with a series of perforations, ff, corresponding in number and size to the punches 0' 6 as shown in said Figs. 3 and 4. As the punch-wheel E is rotated its punches c c are caused to enter, just a little, the perforations on the rim of the die-wheel F, and in this manner a positive motion is imparted to the die-wheel F from the punchwheel E. I fy are the ends or trunnions of the shaft f, and they are free to rotate in bearings g y, secured in a suitable manner to the under side of table-top a or supports a. The trunnions f 3 f of the shaftf are free to move longitudinally in their bearings g y, to permit the dieiwheel F to adjust itself automatically and longitudinally to any inequalites in the positionand arrangement of the punches e 6 If so desired, the shaft f may be made stationary and the die-wheel arranged to run and slide freely upon said shaft to equal advantage. This is a very essential feature, as it is very difficult to arrange the punches e mathematically correct on the wheel E, one in relation to the others; and as itis'equally difficult to drill the perforations f f mathematically correct and in a line with each other,

we so arrange the die-wheel F in its bearings that it shall be free to adjust itself longitudinally in relation to the punch-wheel E.

g g are screws by means of which the bearings g g are secured to the support at below the table a, as shown in Figs. 3 and 4. The bearings g g are preferably made as two independent parts that are secured together by means of set-screws g g, (shown in dotted lines in Fig. 4,) after the trunnionsf f of the shaftf have been located in the holes in said bearings. a isa slot through the table-top a, into which a portion of the die-wheel F projects as it rotates, and receives the punches e" 6 into its perforationsff during the rotation of the punch-wheel E.

H is avertically-adjustableguide-platehaving a slotted opening, h, for the punch-wheel E to pass through, as shown in Figs. 3 and 4, which guide-plate, after beingadjusted so as to leave a little space between its under side and the,top of table a for the material to pass through, is secured to one side of bearing 12 by means of setscrews h h, passing through slot-holes in the vertical upward extension H of the said guide plute H, as shown in dotted lines in Fig. 4.

The object of the guide-plate H is to prevent the paper or material that is being perforated from being carried around the punchwheel E and to guide it forward in a straight line on the table a. The guide-plate H is made vertically adjustable, so as to compensate for differences in thickness of materials that are to be perforated. v I is a paper-gage arranged on top of table a at a right angle to the shaft 0, and it is made adjustable to and from the punch and die wheels E and F by means of set-screw or thumb-nut z, the head of which is guided in the groove a made in the upper side of table a, as shown in Fig. 1. For the purpose of guiding said gage I accurately during its adjustment to and from the punch and die wheels E F, we provide it near its ends with guideblocks t t", adapted to slide in parallel grooves a a in table a, as shown in said Fig. 1, such gage being similar in construction and operation to the adjustable work-rests used on circular-saw benches.

The operation is as follows: The shaft 0 and its punch-wheel E are set in a rotary motion, and as the punches e 6 enter the perforations f f on the die-wheel F the latter are set in a positive rotary motion corresponding to that of the punch-wheel E. The paper to be perforated is then introduced at as between the under side of the guide H and top of table a and fed forward until its front end is taken hold of by the punches e e and the die-wheel F and caused to move onward and to be perforated by the punches e e, passing through the paper and entering the perforations f f in the diewheel F. During such operation one edge of the paper or material is guided against the gage I, which is set and adjusted at a proper distance from the punch and die wheels, according to the distance the row of perforations is to be made from one edge of the paper. I

In Fig. 5 is shown a modification of our invention as adapted for perforating the paper at one operation with a number of parallel lines of perforations, for which purpose a series of punch-wheels, E E, are secured'at a proper distance apart on the rotary shaft 0, each punch-wheel being constructed as hereinabove fully described, and having arranged below it and the table a the die-wheel F, located in bearings g g, precisely in the same manner as shown in Figs. 3 and 4, the diewheels being free to move in the direction of their shafts, to compensate for inaccuracies in the location of the punches and the perforations on the respective punch and die wheels E and F.

This machine is very simple in its construction and accurate in the execution of the work, on account of the longitudinally se1f-adjusting or floating die-wheel by which the punches and perforations on the respective punch and die wheels are made to coincide.

Having thus fully described the nature,con-

struction, and operation of our invention, we i Vitnesses:
